FHIT-SUBSTRATE ANALOG

The structure was published by Lima, C.D., Klein, M.G., and Hendrickson, W.A., in 1997 in a paper entitled "Structure-based analysis of catalysis and substrate definition in the HIT protein family." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1997.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of FRAGILE HISTIDINE TRIAD PROTEIN. This molecule has the UniProt identifier P49789 (FHIT_HUMAN)search. The sample contained 147 residues which is 100% of the natural sequence. Out of 147 residues 126 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms homodimers.
